Weather in August

In August, the average heat index is appraised at a very hot 98.6°F (37°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
